Specification ofLetters latent.` ituitd NGV, 9' 19112@ To all Iwhom t mag/concern:

Be it known that I, ROBERTRWEAVER, a

citizen of'therUnitedStates, and a residentwV of Columbus, in the county of Franklin and State of Ohio, have invented certain new" and useful Improvenientsin Gar-Under-f. frames; and I dohereby declare the follow` ing to be a full, clear, and exact description of the invention, such as will 'enable others skilled in the art to which it appertains to" shall be afforded.

A further object is to so construct a cross tie for a car underframe that the same shall have an integral part at one end projecting above the plane of the upper edge of the tie and so that it shall have an integral inwardly projecting part atitsother end projecting below the lower edge of the tie, whereby the connections of the tie with the center girder and side sill shall extend, respectively above and below the plane of the tie at respective ends thereof.

With these and other objects in view, the invention consists in certain novel features of construction andA combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a transverse sectionalview of a portion of a car underframe; Fig. 2 is a fragmentary view taken at right angles to Fig. l, and Fig. 3 is a view illustrating a modication.

l represents a center girder, and 2 a side sill, the latter being shown as of channel construction.

A plurality of cross ties will be located between the center girder and the respective side sills intermediate of the holsters, but as such disposition of cross ties broadly, is well known in the art, it will suflice for the purposes of this case to illustrate a single cross tie and its connection with the center girder l and one of the side sills.

The cross tie i3 comprises a steel beam ,pressed up in channel forni,having'pits-web portion" extended upwardly `at-the outer end as at 4 and havin'gits Tweb` extended downfwardl'yfat'litsinner endas at 5. u The upper `-fiange"6 lofthfetie isomi-ttedlfrom apart of Vthe upward `webextension ffl andthe lower fiange 7 offtheftie is omitted froinapart of the downward web extension 5. At the `outer end ofthe tiejitsextended web issecin-ed, throughout the vertical extension thereof, to the web of the side sill 2, by means of an angle iron 8. At its inner end, the cross tie may be made with an integral vertical flange 9 throughout the full extend ed end portion of the tie, and securely riveted to the center girder.

Instead of providing the inner end of the tie with an integral vertical flange, said flange maybe omitted and the tie secured to the center girder by means of an angle iron 10, as shown in Fig. 8.

It will be observed that the upper flanged edge of the side sill is approximately in horizontal alinement with the top of the center girder, being but slightly above the same so as to be on the floor line, and Z-beams may be mounted on the cross ties to support intermediate portions of the flooring.

It will also be observed that the outer extended end of the cross tie is disposed wholly below the upper edge of the side sill and its sole function is to provide for an extended connection of the tie with the side sill.

Having fully described my invention what l claim as new and desire to secure by Letters-Patent, is

l. rThe combination with a center girder and a side sill, of a channel beam constitute ing a cross tie extending from the center girder to the side sill, said beam having its web portion extended vertically in opposite directions at respective ends, one of said vertically extended webs being confined between the edges of the side sill and of less height than the depth of said side sill and secured to the latter, and the vertically extended web portion at the other end of the tie secured to the center girder and having a height less than the depth of the latter and confined between the upper and lower edges thereof.

2. The combination with a center girder, and a channel side sill having its flanges pro jecting inwardly.A .of a channel beam consti tuting a cross tie confined below the upper edges and above the lower edges of the cenu ter girder'and side sill, the web of said chanbeam bein extended downwardly at the in# nerend Yt `ereof and having a height less f ed web to the Centergrder.

and a Vside Sill, oit' a cross tie between the center girder and side sill, said cross tie com#y prising a beam having anges at its upper and lower edges, the upper Vflange being`VV omitted at the outer end of the tie and.

than the depth of the center girder, and means securing said last-mentioned extend- 3. The combination with a center girder G opies et this patent may be ,obtained` for the low/effing@ beingbmiaed at the inner end of the tie, the` web of the tie being eX-V tended vertically in oppositedirections at the respective ends of the tie where portionsv of the flanges of the tie are omitted, means securing the extended web at the outer end of the tie to the side. sill, and means securing the 'extended web at the inner-end' of the tie to the `center ginder.
